What can extinguish the sun..? We know water can put out fire. So, what if we manage to bring up a considerably huge mass of water to the sun and drop it there successfully? What will happen? Let's see an approximate amount of energy that reaches the earth from the sun. The earth itself gets about one hundred and seventy trillion kilowatts of energy from the sun in a single day. But is this nowhere near the actual amount that the sun gives out. The sun disburses energy which is two billion times of what we receive at our planet. All these energy is given out to the outer space. So, let's see what will happen if we drop huge mass of water on sun. In order to know about the outcome, we first need to know how water helps put out fire down here at earth. The fire needs a fuel for its existance and when water breaks the supply of combustable fuel, it gets extinguished. But in the case of sun, its not normal fire that we are talking about. The source of energy in the sun is ...
